Steps to reproduce the problem:
1. Enable public session mode in chrome management console
2. Login to a public session on a chrome device
3. Visit a page with a video and try to view fullscreen

What is the expected behavior?
From an end user perspective, the expected behaviour is that when they click the fullscreen icon on a video, it should go full screen.

What went wrong?
On some sites, clicking the fullscreen icon on a video does nothing and gives no user feedback e.g. bbc.co.uk. Other sites, e.g. youtube.com trying to use the fullscreen function effectively breaks the page: the video goes fullpage (not fullscreen) and then won't toggle back to standard size.

Altogether this leads to user confusion, frustration and a less than favourable impression of the device - it appears broken - which is a real shame given that it's otherwise fantastic.

I have seen the chrome policy to disable fullscreen that is automatically applied in public session mode and I've seen other discussions regarding the desire to prevent the Exit Session button being covered etc. However, for us that's not a problem and would need to have the possibility of controlling this policy.

We've been trialling a couple of chrome devices in Public Session mode in order to provide casual web browsing / entertainment facilities to visitors, with a view to replacing a load of our existing devices. The low cost and low management overhead, security, and general ease of use make these the ideal device for our requirements - except the lack of fullscreen capability is a deal-breaker sadly.
